IMPROVEMENT 'IN WlNDQW-SHADE FIXTURES.

Specification forming part of Letters Patent No. 115,178, dated May 23,187i.

I, ALFRED S. DrcKINsoN, of the city of Brooklyn, in the county of Kingsand State of New York, have made certain new and useful Improvements inWindow-Shade Fixtures, of which the following is a specification:

In the ordinary shade-xture, to which this invention relates, and inwhich a roller is used with a spring to wind up the shade, the bearingsand fixtures of the roller are permanently attached to the window, Y andthe loose end of the shade is attached or suspended on the window bymeans of cord and fixtures in such a manner as to enable the operator todraw said loose end over the window to cover it, where desired.

y My invention consists in having also the fixtures or bearings of saidroller, as Well as the loose end of the shade, attached to the windowwith cord and cord-fixtures in a manner capable of moving it up or downover the window, so that, by these means, the entire shade is suspendedon the window, and can be moved up or downto any part across the windowand the shade wound up or unwound to cover any of the space desiredacross the window, by which means "a self-winding shade, withconvenience of controlling and adjusting thesame to cover or uncover thewindow, asV

desirable, 1s obtamed.

In the annexed drawing, Figure l represents a front elevation of thefixture according to my invention, and shown with its application to awindow. Fig. 2 is a rear view of the same; Fig. 3, a vertical centralsection of the same. Fig. 4 represents an end view of the shade-fixturedetached from the window, shown on a somewhat larger scale than in theformer figures. .y

Similar letters of reference indicate corresponding'parts in the severalfigures.

A represents the shade-curtain. Its loose end is bound with theshade-bar B in the usual manner, and to it is secured the cord G, whichpasses through a guide or over a pulley, D, attached on the top of thewindow, and said cord passes from the pulley D down on the rear of theshade, through a guide, E, on the rear of the bar, B, and through aguide, F, on the rear of a bar, Gr, below the rollerof the shade, andsaid cord finally passes through a guide, H, and then passes vthroughand is held fast by means of the catch I located on the lower sill ofthe window. -J represents the shade-roller. It is provided with thespiral spring for winding up the curtain. Its spindles K rest in thebrackets or iixtures L L, which, instead of being secured, as usual, tothe window, are secured to the bar G, winch is detached from the window,but is comblned with the same by means of a secondary cord, M, securedto a rearward-projecting eye of a screw, N, on the rear of said bar; andthe loose end of said cord M passes through a guide, O, and catch l?, onthe bottom sill of the window.

When the shade is required to cover more of the upper part of the windowthe cord C is drawn. When the shade is required to cover more on thelower part of the window the cord M is drawn by the operator.

1n order to uncover on the upper part of the window or on the lower, therespective cord is slackened suiciently until located to cover anduncover the desired portions of the window.

It will be observed the tension of.' th spring of the rolle-r being to.contract and wind up the shade, consequently the shade is suspended in astretched condition over the window, and lies smoothly against thewindow.

By means of having'the cord G to pass through the guides E and F theshade is held to thewindow and prevented from being thrown about by thewind when the windows are left open; and, it will be observed, severalof the cords, C and M, may be employed for large windows or heavyshades.

AThe cord C may or may not pass through the guides E and F, and may passin front of the shade, or may beguided off to the side of the window;and the catches I and I may re= quire, in certain cases, more speciallyfor skylights or church windows, to be located far distant from thewindows or lights suitable for the operator; and additional guides maybeemployed for said cords suitable for the kind of window, the location,and use of op erator.

I arrange and prefer to have the roller J on the lower end of the shade.It may be reversed and applied above.
